FOX Captures its 10th Straight SCORE Desert Series Trophy Truck Victory with Rob MacCachren’s San Felipe Challenge of Champions Win

FOX’s Cactus Cooler equipped bypass suspension — utilizing their unique external cooling system — proved itself to be the competitive advantage in extreme temperatures and terrain.

FOX, the industry-leading ride dynamics company, has extended its SCORE Desert Series trophy truck win streak to 10 with Rob MacCachren’s win at the San Felipe Challenge of Champions. Despite the extreme temperatures that had some drivers contemplating a slower pace, FOX sponsored driver, Rob MacCachren, roared away from the green flag and never looked back.

Typically, the SCORE Desert Series hosts an annual San Felipe 250 race in March when temperatures are milder. However, this year a second race in San Felipe took place because of complications at the Primm course, originally slated to host the fourth stop in the series.

San Felipe is tough enough in the Spring, but paled to the extreme conditions of running it in Summer; temperatures reached north of 105 degrees with up to 50% humidity. The course itself also features some of the most extreme conditions; the start to Borrego is a 60-mile section of bumps that have set the bar for suspension development teams.

While MacCachren’s Baja experience, talent, and finesse have earned him championships and victories over his last 28 years of desert racing, it’s the equipment that tends to hold Rob back from holding it wide open. Not anymore. MacCachren rallied his JIMCO #20 trophy truck from the beginning and by race mile 208, he had a nearly 15 minute physical lead over the nearest competitor. Blasting through 252 miles of desolate rocky earth, MacCachren was unchallenged to the checkered flag.

Averaging 59.94 miles per hour and finishing the course in 4 hours, 12 minutes, and 21 seconds earned Rob MacCachren his second SCORE San Felipe title in the same season. The winning time was actually 5 minutes and 24 seconds faster than his win earlier this year when he was not running the Cactus Cooler.

“The pace this morning was really quick and the truck was working great at the start. It just felt so good. The biggest difference between this race and the one we won here in March is that the shocks have made such a big improvement. We just keep working on the shocks and making them better and better,” said Rob MacCachren. “The track here in San Felipe gets rougher the more we go over it so it’s all about the suspension system.”

“We have been continually testing and improving the external cooling system technology,” said offroad race manger, Todd Tenbroek. “With these improvements, we were able to drop the shock oil temperature by an additional 145 degrees over the last race even with the ambient temperature being 30 degrees higher.”
